Thermo Fisher, 164-0020, Nalgene™ Rapid-Flow™ Sterile Disposable Filter Units with PES, CN, SFCA or Nylon Membranes

Nalgene™ Rapid-Flow™ sterile disposable filter units combine a 1000 mL upper reservoir and receiver with a 0.2 µm nylon membrane for vacuum filtration of laboratory liquids. This configuration uses a 90 mm membrane and is supplied sterile for single-use processing. Nylon is hydrophilic and provides broad chemical compatibility for many aqueous solutions, making the unit useful for filtration of buffers, media components, and other compatible laboratory preparations. The large membrane diameter supports relatively high flow and reduces filtration time for liter-scale volumes. The integrated bottle-and-filter format minimizes assembly steps compared with separate reusable holders and receiver bottles and provides a closed collection vessel after filtration. This case contains 12 complete filter units. Confirm membrane compatibility with proteins, solvents, and critical sample components before use because nylon can bind some biomolecules more strongly than low-binding membrane materials.
